UIBarButtonItem: How can I find its frame?

Question

I have a button in a toolbar. How can I grab its frame? Do UIBarButtonItems not have a frame property?

Answer 1

Here's the way to do it:

-(CGRect)findFrameOfBarButtonItem{
    for (UIView *view in self.navigationController.navigationBar.subviews)
    {
       if ([view isKindOfClass:NSClassFromString(@"_UINavigationBarContentView")])
       {
         UIView * barView = [self.navigationItem.rightBarButtonItem valueForKey:@"view"];
         CGRect barFrame = barView.frame;
         CGRect viewFrame = [barView convertRect:barFrame toView:view];
         return viewFrame;
       }
    }

    return CGRectZero;
}
